Should i go with 31 spline axles?

[AllMotorNotch]

I'm gonna try to build up my rear soon and I'm not sure if I should upgrade to 31 splines or not. My coupe is gonna be mostly street driven under 400horse N/A. I've got an SN95 front 5 lug conv so I have to change the axles either way but I dont know if I should go up to 31 splines and change to a 31 spline trac lok or just buy a set of Mosers and rebuild the current traction lok in the rear. Thanks in advance to anyone that can help me out.

I fyou stay under 400 HP and dont use slicks you can stay with the 28 and rebuild, if you launch hard and use slicks jump up to the 31's or possibly 33's.

Or you could just build it with the 31 splines for any future hp increases you will be doing.
